Two Dow adhesive systems commonly used for a broad range of polyethylene (PE) film packaging applications have been approved as compatible for mechanical recycling following a scientific evaluation by the non-profit, cross-industry initiative RecyClass. The approval covers solvent-free MOR-FREE™ L 75-300/ CR88-300 and waterborne ROBOND™ L-350/ CR-3 lamination adhesives.

A strategic partnership of four technology companies has resulted in a closed-loop recycling model that is sparking new discussions around the role PET-based multilayer will play in tomorrow’s packaging industry.

Sustainable bonding requires combining the highest possible certified bio-based raw material content in the adhesives, low maintenance and energy requirements in the bonding process, high compatibility of the adhesives with existing application systems, and, especially in the packaging industry, high compatibility in terms of downstream paper recycling. All of this must be achieved at competitive prices.
